This document specifies the definitions and requirements for unplasticized poly(vinyl chloride) (PVC-U), polypropylene (PP), polypropylene with mineral modifier (PP-MD) or polyethylene (PE) storm water road gullies intended for non-pressure use only in storm water and combined systems installed to a maximum depth of 4 m from ground level to the lowest point of the storm water road gully. Storm water road gullies complying with this document are intended to be used in pedestrian or vehicular traffic areas outside the building structure. NOTE 1 Products complying with this document can also be used in non-traffic areas. NOTE 2 Storm water road gullies may be subject to national regulation which limit the maximum installation depth and / or local provisions. The installer should check for compliance prior to installation. Storm water road gullies complying with this document are made from a prescribed set of components that are manufactured from unplasticized poly(vinyl chloride) (PVC-U), polypropylene (PP), polypropylene with mineral modifier (PP-MD) or polyethylene (PE) and assembled together. Storm water road gullies complying with this document may be equipped with optional devices (e.g. removable sand or silt bucket, leaf separator etc.), however the performance of these optional devices is not covered within the scope of this document. Storm water road gully components can be manufactured by various methods e.g. extrusion, injection moulding, rotational moulding, low-pressure moulding, blow moulding, thermoforming or fabricated. NOTE 3 Products complying with this standard can be installed in underground applications without additional static calculation NOTE 4 The complete storm water road gully assembly can also include items non-plastic items (near surface or surface components for example) which are not covered by this document. NOTE 5 The complete storm water road gully assembly can be supplied with covers, frame covers and gratings complying with the relevant part of EN 124 [1] which are not covered by this document. However, reference should be made to this document for geometrical characteristics where applicable. NOTE 6 Storm water road gullies can be site assembled from different components, but can also be manufactured as a single unit. - storm water road gullies with or without sand / silt trap; - storm water road gullies with or without water seal preventing odour release; - storm water road gullies where the traffic load will or will not be carried by the complete gully (resp. "Direct loaded storm water gullies" or "Indirect loaded storm water gullies").
